“How do I safely drill holes for the bolts through slate without damaging or cracking it?”
You don’t.
You do NOT want to drill thru your slate roof under any circumstance.Find another location to mount your satellite dish prefferably to an eave thru the siding or on it’s own pole if you must, but not to the slate roof.
Sorry, forgot to mention that the Code also requires that the emergency egress and rescue opening window shall have a minimum net clear opening height of 24″ (R310.1.2)
{This means that when the window opens it shall have an opening of at least 24″ high and can not be considered to conform to the code if the 24″ is reached by breaking our the window.)
R310.1.3 states that the minimum net clear opening width shall be 20″
R310.1.4 states that “Emergency escape and rescue openings shall be operated from the inside of the room without the use of keys or tools.”
Your builder is absolutely correct.
Maryland has adopted the International Residential Code as State Code. This Code can be locally modified in Maryland and is represented under Maryland’s Rehabilitation Codes.
You can see all of Maryland’s Building Code requirements here:

You can confirm what your builder has stated by also calling your town’s building code enforcement office.
But generally speaking, the International Building Code 2003 states:
———————–
“SECTION 310: EMERGENCY ESCAPE AND RESCUE OPENINGS.…..every sleeping room shall have at least one openable (sic: to the outside) emergency escape and rescue opening. {homebild notes: that this emergency opening can be a door or a window.}
…..where emergency escape and rescue openings are provided, they shall have a sill height of not more than 44″ above the floor.
…..R301.1.1 MINIMUM OPENING AREA. All emergency escape and rescue openings shall have a minimum net clear opening of 5.7 square feet (0.532 sq meters){homebild notes: This 5.7 square feet only applies when the sill height is at 44 inches above the outside grade} EXCEPTION: Grade floor openings shall have a minimum net clear opening of 5 square feet (0.465 sq meters)”
{homebild notes: if the window sill on the outisde is less than 44″ above or below the grade [ground] level, the emergency escape and rescue opening can be 5.0 sq feet of net clear opening.)
Bottom line is your builder is correct and at you must have at least 1 window or door that conforms to the emergency egress and rescue requirements in any bedroom.
Hope this helps.
It is better to waterpoof the entire foundation that is under grade especially if this is new construction.
Simpler and cheaper to waterproof now than to deal with leaks and water infiltration later.
Distances from the stove to flammable walls is determined by the manufacturer of the stove and your local building code.
What constitutes a flammable wall and how you can reduce the distance of a stove to a flammable wall is also determined by your local building code.
So what techniques you can use to shorten the distance between a stove and a wall surface needs to be determined professionally by the manufacturer and your building code enforcement office.
Once an approved plan has been derived at by the code official, you can find approved wall treatment products at local fireplace and stove supply retailers.
Do NOT attempt to determine what products to use or how to reduce the clearance yourself.
What do you use?
You use what your local building code says you just use.Insulation manufactuers typically exaggerate the insulation needs for those in a particular area in order to sell mor einsulation than is required.
Your building code office will have strict minimum insulation guidelines as far as insulation is all parts of your house is concerned and is the only one that needs to be obyed and complied with as far as insulation is concerned..
Mold does not require sanding to get rid of it. Simple bleach solutions or mildewcides can kill and remove it with damp mopping.
Stains are another issue altogether and will require sanding the floors.
The problem at this point is not the sheeting but the ventilation.
If the crawlspace is open to the basement at any place, you actually should have no vents open to the outside.
Or if the crawlspace is not open to the basement, the vents should remain closed in summer when surface temperatures in the cool crawlspace can allow warmer outside air to condense.
Your issues now aren’t related to the insulation or sheeting. They are related to the ventilation.
Permanent marker can be removed with denatured alcohol…available from any paint or home improvement center.
Galvanized diamond lath is fastened to the sheathing and or studs behind the foam board using galvanized roofing or aluminum siding nails.
Galvanized lath is designed to be installed horizontally so that the laths will grip the base coat.
Unless your foam board is specifically designed as a backer for stucco applications, you may also still need to install stucco grade housewrap or 15#felt paper as a water barrier between the foam and the diamond lath.
